Acts 19:13-16

13Then certain of the vagabond Jews, exorcists, took upon them to call over them who had evil spirits the name of the Lord Jesus, saying, We adjure you by Jesus whom Paul preacheth. 14And there were seven sons of one Sceva, a Jew, and chief of the priests, who did so. 15And the evil spirit answered and said, Jesus I know, and Paul I know; but who are ye? 16And the man in whom the evil spirit was leaped on them, and overcame them, and prevailed against them, so that they fled out of that house naked and wounded.
